Thermodynamics of Low-Dimensional Trapped Fermi Gases

Figure 2

Normalized thermodynamic susceptibilities as function of the dimensionless temperature for different values of , say, 1/4, 1/2, 3/4, 1, 3/2, 2, and 3. (a) Specific heat per particle at constant generalized volume; the circles mark the corresponding values of at , that is, at the temperature at which has a maximum value; analogously, the triangles do the same at where has a maximum. (b) Isothermal compressibility scaled with ; rhombus marks the corresponding values of at that corresponds to the temperature at which has a maximum value and the triangles do the same as in (a). Notice the nonmonotonic dependence on for .
